This invention relates to intermittently operated mechanism forexhibiting apparatus such as advertising or projection devices driven byspring, weight, electric or other power, and to time or speedcontrolling or controlled mechanism for indicating and recording devicesand the like.

The present invention comprises intermittently operated motor drivenadvertising, in-

dicating or recording apparatus, wherein the apparatus is driven bymotor operated mechanism provided with intermittent releasing mechanismoperatively connected to any suitable member of an adjacent clock, clockf movement or other speed or time controlled mechanism. The relativedirection of movement of both mechanisms is so arranged that anypressure exerted on or through the releasing mechanism upon aconnect-ing member ot the controlling mechanism will be in the directionof motion of such connecting member, so that there will be noretardation or braking action on the controlling mechanism.

The intermittently operated mechanism may be driven by its motor throughtoothed rearing of which any one or more shaft or shafts of theintermittently released mechanism has a crank and a connecting rod cr;-tending from the crank pin to a notched or toothed wheel fixed on asuitable shaft of the clock train or other speed or time controlledmechanism, the notched wheel being?I driven at a slower peripheral speedthan the crank pin, the free end of the connecting` i l being providedwith a transverse pin or member adapted to be engaged by the teeth orthe like of the notched wheel and hold or d the crank until the notchedwheel has moved sufficiently to allow the crank to turn over dead centreand enable the motor to rotate the crank so that it will perform thereturn movement or a series of such movements of the connecting rodnecessary to carrj,T its transverse pin into a position in which it willbe engaged by an adjacent tooth of the notch.- ed wheel, and theoperation is repeated. The connected rod is preferably made slightlyextensible and compressible and restorable lav by spring action when theextending or ci pressing force is removed.

The motor driven advertising, indicating or recording devices may bemounted on discs or drums arranged on vertical or hori- Zontal axes, aconvenient method being to support them on a disc mounted on a verticalaxis running in jewel or other suitable trictionless or practicallyfrictionless bear. or pivot centres, and the devices may be sup'L portedby gravity 0r otherwise in recesses or guides provided in the face ofthe disc at uniorm distances apart circumferentially. The devices may betransparencies to use in illuminated or projection apparatus.

The movement of the toothed wheefL be controlled by clock escapeinent meanism and the clock train provided with an ordinary clock face providedwith hour or minute hands.

A manner of carrying out the invention is illustrated by theaccompanying drawings wherein Figure 1 is a front elevation of a clockcase containing the device, Figure 2 a section side elevation showingdiagrammatically the main elements of the apparatus, Figure 3 a diagramof the intermittently operated mechanism, when using two motors, Figure8a is a diagram of the intermittent mechanism when using one motor only,Figure a a plan of the same, Figures 5 and 6 alternative details ofholders for the transparencies or slides, and Figure 7 is a detail oithe train mechanism.

In these drawings 2 is a casing containing a translucent clock dial 3and a screen 8 which may be a. sheet of frosted glass, a is a disc onwhich transparen devices 6 or slides containing the matter to beexhibited are arranged, l a lamp arranged above the transparencies 6 andalso behind the translucent clock dial 8. The rays from the lamp l passthrough a condenser lens 5 arranged above the transparencies 6, that isat a position under which each of the transparencies 6 will be movedintermittently so that the projected rays will pass downwards on to areflector 7 inclined in such a manner as to reflect the projected rayson to the screen 8.

The disc a carrying the transparencies 6 is rotated a shatt 9 mounted ateach end in adjustable pivot bearings 10 and 11 and carrying a toothedmitre or bevel wheel 12 arranged to mesh with a toothed pinion 13mounted on a shaft lelcarrying a pinion and a crank 16.

ln order to allow tor the taking up of play between the parts, thetoothed pinion 13 is not fined directly to the sha t 1st but connectedthereto by means ort a spring 13a ot which one end is fastened to thewheel 13 and the other to collar 13 fixed on the shaft 14 and throughwhich power is transmitted. Such means tor taking up the play may7however, be arranged at any other suitable portion ot the gearing.

rlhe disc carrying the transparencies 6 when arrested at each periodicmovement is retained by pawl #l5 pivoted to a support member 49, thetree end of the pawl being arranged to engage with a notch or groove 16provided ir the tace ot the disc a.7 the number oit notch piuwided inthe disc correspending` to the number of transparencies 6. The pinion 15forms the last wheel et a train of toothed gears 1r, 16, 197 20, 21, 23ot which 23 is dir/en by a spring 24 in a manner similar to a clockjthereby comprising a motor driving` the disc a, containing thetransparencies 6 or slides containing 'the matter to be exhibited d alsodriving a crank 16 which is connected by a connecting rod 25 toreleasing mechanism comprising a second train ot wheels. Any suitablegovernor such as an air vane or ily wheel 9a` ma;Y be provided on thistiret mentioned train of wheels.

The second train oi wheels in the example shown is driven by a spring 27in a manner similar to the tirst trein described above. The spring Q?drives through a train of toothed gears Q8. S29, 30. 31. 32 and 33, anotched r toothed wheel 3l. and on the shaft 35 carrying the toothedwheel 3% also a toothed wheel 36 `gearing with a pinion 37' on a shaft38 carrying an escapement wheel 39 with which cto-operates an escapementl0 controlled by a pendulum 41 in the usual manner. rllhe toothed wheelot the time controlled train. gears with a wheel L14 driving the trainof the hands 3a, 3l) ot the clock dial 3.

The two trains ot wheels are carried Vin bearings in front and rearpla-tes 42 and 43 as in ordinary clock work actions.

The driving` powers ot the two springs 24.- and 27 are approximately otequal strength. and the trains are so designed that the notched ortoothed wheel 34 makes one revolution in about the same time that thecrank 16 makes twenty revolutions, and the wheel 34 contains ninenotches in its periph-er. The crank 16 and the notched or ratchet wheel3d form interconnecting transmission members connected together by theconnecting rod 25.

The shaft 14 carrying the crank 16 is approximately at the same level asthe shaft ot the notched wheel 34, and the connecting r'od .25 extendsto the wheel 34 and has at its free end a 'forked portion carrying atransve member or pin which engages the notches on the upper portion otthe notched wheel 34.

The function of the connecting rod 25 is to arrest or delay the motionof the crank 16 at or during a `predetermined period corresponding tothe desired pe iod of projection ot the transparencies 6 andcorresponding to the timing by the clock train. To eli'lect thisfunction ot the crank 16 and notched wheel 3ft are arranged to rotate inthe same dircction, and the crank 16 arranged to impart a pull on theconnecting rod :25 during the half revolution when the crank 16 isuppermost, that is to say above the shaft 14, and its direction otmotion is away from the notched wheel 3st of which the upper notches areturning slowly towards the crank 16. The pin ot the connecting rod isheld by one of the notches in the wheel 3-1 while approaching the crank16 and until the crank 16 reaches the position furthest from the notchedwheel 34, whereupon the crank 16 continues to turn without anyrestraintdownwards an d backwards beneath its shaft 1A by the action ofthe spring 2st, and thc connecting rod is similarly driven back untilthe connecting rod pin is immediately disengaged trom the notch in thewheel 3l and slips back into the next notch at or before the instantwhen the crank has completed the halt turn below its shaft. The crank 6then contnue-s to turn above its shaft until its rotation arrested ordelayed by the pin dropping by gravity and engaging the bottom ot thenotch it has just entered, when the action is repeated.

In order to provide a movement ot the disc or slide holder equivalent toone complete revolution of the crank 16 the teeth ot the mitre wheels 12and 13 operating the slide holder a may be constructed with tree playtor instance between the faces ot the teeth ot the wheels 12 and 13, soas to allow the slide holder to continue to revolve by its own momentumafter each periodic arrest ol' the dgiving mechanism until such play istaken up and the slide holder fr is engaged and held by the pawl 45droppingr into the groove 46 as described. Upon the motion of the discholder a being arrested by the takingr up ot the play between the partsor by the action ot an interposed spring it may be held by a suitableratchet device from any tendency to recoil.

The throw of the crank 16 is arranged to bc greater than the distancebetween the bottoms oit consecutive notches in the wheel 34 for thepurpose of ensuring the free move- (ifi ment of the pin from one notchto the next and to allow the crank 16 to run well forward towards theextremity of its travel before it is arrested or delayed by theengagement of the pin 35 in the next notch cf the wheel 34 as described.

In order to allow of an increase in the ferward movement of theconnecting rod 25 and also to protect the train of the notched wheel 34from shock the connecting rod 25 may be made of a light strip of metalor other suit-- able material and bent or waved as at 23a or otherwisemade extensible and contractabie, and thereby allow of an extension inits length when arrested by the notches in the wheel 34 and soaccommodate pull or momentum of the train driving it.

In a modification of the apparatus the spring 27 and toothed wheels 2Sand 29 are dispensed with and the wheel 30 driven from the wheel 22 bymeans of intermediate wheels 4:7 and 470 of equal size shown in Figure 3in dotted lines. In this modification the wheel 47 is free on the shaft47a and is connected to the wheel 470 by a power m i sur ing spring 47?)as shown in Figure 7. rlhe shaft 47a is driven by the fixed wheel 470from the wheel 22 and transmits the power through the spring 475 and thewheel 47 to the wheel 30 of the clock train. The intermediate wheels 47and 470 may be substituted by any other suitable transmission mechanism.

The transparencies 6 are held by gravit-v in angle pieces 48 arranged toform corner pieces extending from the disc a at equal distances fromopenings t2 provided for the projection rays. Instead of the anglepieces i8 the transparencies may be arranged to fit in slides 50 (seeFigure 6) fastened over the openings a2 by screws or rivets passingthrough the holes 51, the openings a2 being made rectangular tocorrespond to the rectangular opening 53 provided in the slides 50.Figure 5 illustrates a slide for holding charts or other devices for usewith apparatus not constructed for projecting transparencies.

The motor operated mechanism may be arranged to drive switching devicesfor electrical circuits, or relay mechanism.

The power expended by the crank driving` train may be employed to impartimpulses, or control impulses given, to any desired mechanism for anydesired purposes, by direct mechanical action or interposition of parts.electric contacts and similar means.

A device of this character is illustrated by Figure et wherein the disca is of metal and is provided. with a number of circumferentially spacedblocks a3 on which bears an electric contact brush a4, the brush a4being connected to one lead a5 of an `electric supply circuit, while theother lead a6 of the electric supply circuit is connected to the disc athrough the shaft 9.

Further the delay or arrest of the crank 16 may be effected upon itspassage beneath its shaft instead of above it as shown in IV igure 3,and the pin 35 at the forked end of the connecting rod 25 in such casemay press against the notches on the under portion of the notched wheel34e, which are moving away from the crank 16.
